Well, it has begun. Even though my 3.0 has never failed me... it has let me down in terms of power and MPG. I did a lot to it, and plan to transfer what is compatible to the 3.4 accessory wise. I am looking forward to being able to complete some road trips with a little more authority in the passing lane.
Donor motor: 3.4 out of a 96 4Runner, 5spd.
There are some mighty good writeups already here on YT with plenty of detail. Mt. Goat
(link) and Breknraj
(link) are just a couple of shining examples that I plan to have guide me.
There will be a few things different with my swap however that may help others.
1. I have an SAS
2. I have dual cases courtesy of Marlin and their various adapters (23 spline throughout)
3. I plan to use headers
4. I plan to wire it myself (but have ORS bookmarked should I fail
)
5. I plan to do a custom filter/ intake similar to what I built for my 3.0
6. No supercharger
7. No bodylift (hood, meet cut off wheel... cut off wheel, meet hood
)
I'll keep this thread updated... but my progress will be slow. Just starting to tackle the wiring at this point. I will then do some maintainence on the 3.4 such as timing belt, water pump and anything else that's easier to do with the motor out of the 4Runner.
On with some pics. Current 3.0 that is now in the way
Donor motor:
Electrical spaghetti
I have dowloaded basically the entire manual for the 96 4Runner from TIS
(link) and have already found the $10 a day charge more than worthwhile.
So... wish me luck...
I am also looking for suggestions on sparkplugs, wires, air filter (cone type, not stock), oil filter, additional mods or anything that I might be missing. By the way, I have no plans to tear down the motor and do internal upgrades at this time. I will run it stock for a year or so, and then think about getting some more performance if I feel the need.
I did already have one wiring question... but didn't want it to get buried here.
